Stereolithography machine with facilitated initialization

Stereolithography machine comprising:

• a tank suited to contain a light sensitive resin, provided with a bottom;
• a modelling plate facing said bottom;
• a moving unit suited to move said modelling plate according to a direction of movement orthogonal to said bottom;
• a coupling unit suited to associate said modelling plate with said moving unit , comprising a first coupling member integral with said moving unit and a second coupling member integral with said modelling plate and movable with respect to said first coupling member at least according to said direction of movement , in such a way as to define a plurality of mutual configurations;
• tightening means suited to be operated to lock the movement between said coupling members in any of said mutual configurations in such a way as to make said modelling plate and said moving unit integral with each other;
• characterized in that said tightening means are suited to be operated so as to tighten said coupling members against each other according to a tightening direction that is orthogonal to said direction of movement.
